DSA_generate_key

 #include <openssl/dsa.h>
 int DSA_generate_key(DSA *a);

DSA_generate_key() expects a to contain DSA parameters. It generates a new key pair and stores it in a->pub_key and a->priv_key.

The PRNG must be seeded prior to calling DSA_generate_key().

DSA_generate_key() returns 1 on success, 0 otherwise. The error codes can be obtained by ERR_get_error(3).

DSA_generate_key() is available since SSLeay 0.8.
